im still kind of new but from what i know and what i have used (RT/egrip):
no matter what trigger your put on unless you have a super fast finger you'll never beat out a RT or EGrip. these are not actual triggers but they are firing systems that can give u semi-auto, auto, etc, and basically increase the bps (balls per second) shot from your gun.

the trigger is just to help comfort and expand the sweet spot for the RT. it is up to the RT , egrip, or the person to shoot faster.

PS. try to post all your questions in one thread its easier for everyone and you lol
